A manometer of mercury indicates a reading of 1 m when the fluid pressure, water, ( $P_1$ ) at point A is 0.065 m Hg vacuum. Determine the fluid pressure, oil, ( $P_2$ ) at point B.

$P_1$

$P_2$

$0.065 \ \si\m$

$0.035 \ \si\m$

$0.065 \ \si{m \ Hg}$

Given:

$h_{water}$ = (0.35 + 1)m = 1.35m

$h_{oil}$ =0.35m

$h_{Hg}$ =1.00m

$\gamma_{Hg}$ =133 $kN/m^3$

$\gamma_{oil}$ =8.95 $kN/m^3$

$\gamma_{water}$ =9.80 $kN/m^3$

Find:

The fluid pressure $(P_2)$ at point B.
